Stimulus is defined as any change in the environment or form of energy that affects an organism’s behavior or physiological state. Stimuli can be external or internal, and they can elicit a response or alter behavior. Example A loud sound (stimulus) in the environment may cause a person to jump or turn toward the noise. The sound serves as an external […]
Social Validity refers to the extent to which the goals, procedures, and outcomes of an intervention are meaningful, acceptable, and relevant to the individual receiving the intervention, as well as to the stakeholders (e.g., parents, teachers, and caregivers). It ensures that the behavior change strategies and outcomes not only align with evidence-based practices but also hold value in
SDp refers to a discriminative stimulus for punishment. It is a specific stimulus in the presence of which a particular behavior is likely to be punished. When an individual encounters this stimulus, they learn that engaging in a certain behavior will result in an aversive consequence, which decreases the likelihood of that behavior occurring in the future. Example A child learns that touching a
Response Cost is a type of negative punishment where a learner loses access to positive reinforcers or privileges as a consequence of engaging in undesirable behavior. The removal of these reinforcers is intended to decrease the future occurrence of the problem behavior. Example A child earns tokens for completing tasks, which can be exchanged for a reward. If the child engages
A response is a single occurrence or instance of a behavior. It refers to a specific action or behavior that happens at a particular moment in time. Example A teacher asks a student a question, and the student raises their hand to answer. The act of raising the hand is a response—a single instance of behavior in reaction to the teacher’s question.
Reprimand is a form of verbal correction in which the teacher, therapist, or caregiver tells the learner to stop engaging in a particular behavior. Reprimands are typically used to decrease the likelihood of the behavior occurring again in the future. Example A child is running in the hallway, and a teacher says, “Stop running!” The verbal reprimand informs the
Repeatability refers to the idea that behaviors can occur more than once and, therefore, can be counted or measured over time. It highlights that behaviors are not one-time events but can be repeated and measured to assess frequency or other relevant dimensions. Example A teacher tracks how many times a student leaves their seat during a 30-minute period.
A reinforcer is any consequence or stimulus that, when presented after a behavior, increases or maintains the likelihood of that behavior occurring again in the future. Reinforcers can be positive (adding a pleasant stimulus) or negative (removing an aversive stimulus). Example A student completes their homework, and as a result, the teacher gives them extra playtime during recess. The extra playtime serves
Professional Practice of Behavior Analysis refers to the application of principles and techniques of Applied Behavior Analysis (ABA) by individuals across various professions to improve socially significant behaviors. These professionals utilize ABA methods to assess, intervene, and modify behavior in a wide range of settings, including education, therapy, healthcare, and business. Example A school psychologist who uses ABA to design behavior intervention plans for students

The Premack Principle, also known as “Grandma’s Law,” states that a more preferred activity can be used as a reinforcer for a less preferred activity. In other words, if an individual engages in a less preferred behavior, they can access a more preferred activity as a reward. This principle is used in behavior modification to increase the likelihood of
